RoHS non-compliant per the listing, which matters for markets requiring RoHS conformance; the lead-free variant S11B-XASK-1(LF)(SN) covers that need.
Compared to the 10-position S10B-XASK-1(LF)(SN) and the 12-position S12B-XASK-1, this 11-position version fills the gap for BOMs that need an odd circuit count in the same 2.50 mm pitch, right-angle, board-lock footprint.
The lead-free version S11B-XASK-1(LF)(SN) is the direct RoHS-compliant equivalent, sharing the same 11 positions, 2.50 mm pitch, right-angle orientation, and board lock.
Yes, this header is designed to mate with JST XA series crimp receptacle housings that accept the corresponding male pin contacts. The locking ramp on the header engages the housing latch for secure retention.
The pinout follows the standard single-row 11-position layout at 2.50 mm pitch, with all positions loaded. The base product number is S11B-XAS.
